Desastre En Chernobyl

CHERNOBYL DISASTER:
The Chernobyl disaster was a nuclear accident happened at the Chernobyl nuclear power plant (Ukraine) on April 26, 1986. Considered together with the Fukushima I nuclear accidentin Japan, 2011, as the most serious in the International Nuclear Event Scale (major accident, level 7). It is considered one of the greatest environmental disasters in history.
One day, during atest that simulated a power outage, a power surge in the nuclear reactor is produced overheating nuclear reactor core, leading eventually the accumulated hydrogen explosion in interior. The amount ofuranium dioxide, boron carbide, europium oxide, erbium, and zirconium alloys graphite expelled, 4 radioactive and / or toxic estimated was 500 times greater than that released by the atomic bomb droppedin Hiroshima 1945 directly caused the death of 31 people and forced the Soviet government to evacuate 116,000 people causing international alarm radioactivity detected in at least 13 countries inCentral and Eastern Europe.
After the accident, began a massive process of decontamination, containment and mitigation which played about 600 000 people called liquidators in surrounding areas to thecrash site and isolated an area of ​​30 km radius around the nuclear plant known as Area alienation, which is still in force. Only a small part of the liquidators were exposed to high levels ofradioactivity. Work on the reactor containment avoided a second explosion hit the dramatic consequences that could have left Europe uninhabitable.
Two people, plant employees were killed as a direct result ofthe blast that night and 31 in three months. Thousand people received large doses of radiation during the first day after the accident, 200,000 people received about 100 mSv, 20,000 about 250 mSv and500 mSv some. In total, 600,000 people received doses of radiation decontamination work after the accident. 5,000,000 people lived in contaminated areas and 400,000 in severely contaminated areas,...
